我想移動到名爲DetailView的nib文件而不是警報。我無法弄清楚如何讓這個工作。我想把數據從我這裏帶到新的Wiew。我真的試圖讓這個工作,但我無法弄清楚。如何在表視圖中獲取詳細的詳細視圖而不是警報

謝謝你的幫助。我仍然沒有得到它的工作。我有點不確定如何以及在哪裏聲明navigationController以使其工作。 – user1301000 2012-03-30 07:13:12
查看UIViewController和UINavigationController的文檔以獲取更多信息。導航控制器是UIViewController的一個屬性,應該在大多數情況下已經存在。你只需要調用它。 – Rob 2012-03-30 10:50:48
再次感謝。我越來越接近:)我有一個NSLog的詳細信息頁面設置。當我運行時,我可以看到數據到達控制檯中的詳細視圖,但視圖不會更改。我在IB中遺漏了什麼? – user1301000 2012-03-30 13:37:20
